Mucus, phlegm, and sputum in cystic fibrosis.
Although some clinicians still believe that cystic fibrosis (CF) lung disease is largely due to hypersecretion of very viscous mucus, it has never been demonstrated that there is mucus hypersecretion in CF and it is clear that there is almost no intact mucin (the principal polymeric component of normal mucus) in CF sputum. CF sputum has lower viscosity when compared to asthma or bronchitis sput...
متن کاملSputum induction in young cystic fibrosis patients.
A culture from the lower airway secretions is the optimal sample to guide antibiotic therapy in cystic fibrosis (CF) lung disease. The authors therefore examined whether sputum induction is an efficient, safe and acceptable procedure in CF children without spontaneous expectorations. Nineteen patients were studied. Their mean age (range) was 8.6 yrs (4.3-15.2 yrs). Their mean forced expiratory ...
متن کاملSputum itraconazole concentrations in cystic fibrosis patients.
Itraconazole diffusion in sputum was studied in 11 cystic fibrosis patients with allergic bronchopulmonary aspergillosis. There was a high interindividual variability in sputum itraconazole concentration and sputum/serum drug concentration ratio. Three children had sputum drug concentrations before oral administration that were lower than the itraconazole MIC at which 90% of Aspergillus fumigat...
متن کاملGlycosylation of sputum mucins is altered in cystic fibrosis patients.
Cystic fibrosis (CF) is characterized by chronic lung infection and inflammation, with periods of acute exacerbation causing severe and irreversible lung tissue damage. We used protein and glycosylation analysis of high-molecular mass proteins in saline-induced sputum from CF adults with and without an acute exacerbation, CF children with stable disease and preserved lung function, and healthy ...
متن کاملAntioxidant properties of cystic fibrosis sputum.
Oxidative stress is a likely contributor to the pathogenesis of cystic fibrosis (CF) lung disease. However, hydrogen peroxide (H(2)O(2)), a physiological oxidant, is not elevated in CF exhalates. H(2)O(2) may be neutralized by antioxidants in CF airway secretions. The H(2)O(2)-detoxifying capacity of CF airway secretions, obtained via sputum induction, was studied in an in vitro H(2)O(2) cytoto...
